Abstract

A new layout system for analog cells is presented. Unlike most other systems, the problem of interaction is addressed: the goal is to enable an analog expert to achieve the layout of common analog cells, in less than half a day, the final result being as good as a totally handcrafted layout. The system is divided into two main parts: first, the primitives which are necessary to generate the layout of analog cells (generation of devices, associations and symmetries of basic elements, interactive routing); second, an easy to use graphic environment, which provides enough interaction in the manipulation of basic structures to enable the designer to reach the layout he desires. Many real cells have been laid out using this tool. Some final results on silicon are reported.<>
一种自定义模拟单元布局的新方法
提出了一种新的模拟单元布局系统。与大多数其他系统不同,解决了交互问题:目标是使模拟专家能够在不到半天的时间内实现常见模拟单元的布局,最终结果与完全手工制作的布局一样好。该系统主要分为两个部分:第一,生成模拟单元布局所需的原语(器件的生成、基本元素的关联和对称、交互路由);其次,一个易于使用的图形环境,在基本结构的操作中提供足够的交互,使设计师能够达到他想要的布局。许多真实的细胞都是用这个工具绘制出来的。报道了硅的一些最终结果。
